在 MapBox 上添加标记的最佳方式是什么？

Question

众所周知，mapbox.addMarker() 已弃用！我试图找出使用 Symbol Layer

添加标记的新方法

我正在使用这段代码，它对我有用！但是每次我想添加标记时它都会重新定义地图的样式

代码如下：

 //Add Marker to the Map
    public void addMarker(@NonNull LatLng point) {
        Feature feature = Feature.fromGeometry(Point.fromLngLat(point.getLongitude(), point.getLatitude()));
        mapboxMap
                .setStyle(new Style.Builder()
                        .fromUri("mapbox://styles/mapbox/cjf4m44iw0uza2spb3q0a7s41")
                        .withImage(ICON_ID, marker)
                        .withSource(new GeoJsonSource(SOURCE_ID, feature))
                        .withLayer(new SymbolLayer(LAYER_ID, SOURCE_ID)
                                .withProperties(PropertyFactory.iconImage(ICON_ID),
                                        iconAllowOverlap(true),
                                        iconIgnorePlacement(true),
                                        iconOffset(new Float[]{0f, -9f}))));

    }

所以，我想知道在最新的 MapBox SDK 8.5.0

上添加标记是否有正确或更好的方法

谢谢！

mapboxMap.setStyle(Style.MAPBOX_STREETS, new Style.OnStyleLoaded() {
                    @Override
                    public void onStyleLoaded(@NonNull final Style style) {
                     AddSanciangkoStreet(style);
                     SanciangkoStreetMarker();
             }
  }

private void AddSanciangkoStreet(@NonNull Style style) {
        style.addImage("sanciangko-street",
                BitmapUtils.getBitmapFromDrawable(getResources().getDrawable(R.drawable.floodicon)));

        style.addSource(new GeoJsonSource("sanciangkoFlood1-source-id"));

        style.addLayer(new SymbolLayer("sanciangkoFlood1-layer-id", "sanciangkoFlood1-source-id").withProperties(
                iconImage("sanciangko-street"),
                iconIgnorePlacement(true),
                iconAllowOverlap(true),
                iconSize(1f)
        ));
}

private void SanciangkoStreetMarker() {
        if (map.getStyle() != null) {
            GeoJsonSource sanciangkoFlood1 = map.getStyle().getSourceAs("sanciangkoFlood1-source-id");
            if (sanciangkoFlood1 != null) {
                sanciangkoFlood1.setGeoJson(FeatureCollection.fromFeature(
                        Feature.fromGeometry(Point.fromLngLat(123.895801, 10.297237))
                ));
            }
        }
}
